Truthful mechanism design for transmission scheduling in beyond wireless body area networks
MetadataShow full item record
As an enabling technology for supporting ubiquitous physiological monitoring of human bodies, wireless body area networks (WBANs) has been proposed as a promising paradigm for future wireless communications, and can provide a lot of benefits in various perspectives. One major application of WBANs is the use for healthcare services. The implementation of WBAN-based remote medical systems can significantly alleviate the financial and social burdens resulting from the growth of aging population, the increasing demand for high-quality treatments and the rising costs, as it can offer pervasive healthcare monitoring, computer-assisted rehabilitations and emergency notifications. Because of these, a lot of research efforts have been made in this area. However, the technical issues related to data packet transmissions in beyond-WBAN communications (i.e., the information exchanges between WBAN-gateways and the remote facilities), though of high importance, have not been well studied. This thesis particularly emphasizes on studying the beyond-WBAN transmission scheduling by applying the mechanism design technique for achieving high network efficiency (e.g., social welfare maximization or operation revenue maximization), ensuring the fulfillment of desired priority-aware quality-of-service (QoS) and preventing any untruthful strategic bahaviors from smart WBAN-gateways. Specifically, i) we start by proposing a truthful mechanism for delay-sensitive transmission scheduling with homogeneous packet transmission time in the beyond-WBAN; ii) by relaxing the assumption of homogeneous packet transmission time and defining a discretized priority classification fitting the existing IEEE standards for WBAN-applications, we then design a novel truthful mechanism for supporting multi-class prioritized delay-sensitive beyond-WBAN transmission scheduling; iii) with the further consideration of a more general transmission service process and the relaxation of the fixed priority requirement, we redesign a truthful mechanism for managing delay-dependent dynamic prioritized transmission scheduling; and iv) for dealing with applications with stringent delay limits in the beyond-WBAN transmission, we extend the previously employed delay-sensitive transmission scheduling framework to a delay-constrained one and develop a corresponding truthful mechanism for delay-constrained prioritized transmission scheduling. Both theoretical analyses and simulations are conducted to evaluate the performance of the proposed mechanisms.
